I'm not 100% positive, but I dont think the 555L will work on the 2003. I'm pretty sure that the 2003 trucks use a databus. Check into getting a databus bypass module.

555L works fine on the 2003 tahoe's.

the 555l does work on the chev truck. make sure the wire that you tag are no more than 2 inces from the passlock plug where it goes in to the key !!!!!
